' 1 Claim. 01. 240-108) The present invention relates to a lamp shadeand more particularly to a decorative lamp shade for Christmas trees andthe like.

The general object of the present invention is the provision of a lampshade of the character described having one or more decorativetranslucent panels adapted to be illuminated by the light bulb insidethe lamp shade.

Another important object of the present invention is the provision of alamp shade of the character described which is easily taken apart andreassembled so that the decorative panels may be changed if desired.

Another important object of the present invention is the provision of alamp shade of the character described which may be easily and quicklyfitted to standard small size sockets and light bulbs such as those usedfor Christmas trees.

Another important object of the present invention is the provision of alamp shade of the character described which is simple and inexpensive tomanufacture on a mass basis.

The foregoing and other important objects of the present invention willbecome more apparent during the following disclosure and by referring tothe drawings in which:

Figure 1 is a perspective view of the lamp shade;

Figure 2 is a perspective view of the exterior body frame;

Figure 3 is an elevation of the sheet forming the decorative panels,said sheet being shown in flat state;

Figure 4 is a perspective view of the folded sheet;

Figure 5 is a perspective view of the insert to hold the sheet ofdecorative panels in place within the body frame;

Figure 6 is a perspective view of the sheet and insert being assembled;

Figure 7 is a perspective view showing how the sheet and insert areinserted within the body frame;

Figure 8 is a perspective view of the assembled lamp shade showing howit is attached to the socket;

Figure 9 is a partial cross-section of the lamp shade; and

Figure 10 is a longitudinal section of the lamp shade.

Referring now more particularly to the drawings in which like referencecharacters indicate like elements throughout, the lamp shade is madeessentially of three detachable parts namely, an external body frame 1,a sheet of translucent material 2, which constitutes the threedecorative panels 3 of the lamp shade, and an insert frame 4 whichserves to hold the panels 3 in proper position within the body 1.

The body 1 has preferably an equilateral triangular cross-section andhas three side faces which are mutually inclined and are each providedwith a window 5 of ogival shape. The frame 1 consists in cross-members 6making an equilateral triangle lying in a plane perpendicular to thelongitudinal axis of the body 1. Three upright members 7 extend from theapices of the triangle formed by the cross members 6 and are disposed atright angles lice to the plane of said triangle. The uprights 7 consistin a straight portion 8, which is common to two adjacent faces of thebody 1, and in branch curved portions 9 defining the ogival form of thewindow 5. Therefore the body 1 has three straight portions 8 and sixcurved branch portions 9, the latter meeting together at their upperends. A curved triangular-shaped web member 11 is disposed between eachpair of adjacent curved branch portions 9 and is provided with anaperture 12. The web members 11 serve to give rigidity to the body 1 andalso to connect to said body a sleeve member 13 of cylindrical shapewhich projects outwardly partly from the top end of the body 1 andprojects within said body, as shown more particularly in Figure 2, andis provided at its lower inner end with a restricted opening 14 (Figure9). The sleeve 13 is adapted to receive a socket A for a light bulb B.The socket A and light bulb B are of the type used for Christmas trees.The neck part of the light bulb B engages the edge of the bottom of thesleeve 13 so that the lamp shade is retained on the socket and lightbulb through said sleeve 13.

The sheet of translucent material 2 is cut out to form three ogivaldecorative translucent panels 3 which are connected along their sideedges (Figure 3). The decorative panels are preferably coloured so as toimpart an attractive decorative effect when lighted by the bulb B. Thesheet 2 is folded along the side edges of the panels 3 and is insertedfrom the bottom end of the body 1 into the same so that each panel willregister with a window 5 of the body 1, the edges of the panels engagingthe inside face of the marginal portions of the uprights 7 and crossmembers 6. The sheet is maintained in this position by means of aninsert frame 4 which has substantially the shape of the body 1 but hassmaller dimensions so as to fit inside the body 1 and contact the innerface of the sheet 2. More particularly, the inside frame 4 consists inthree ogival frames 15 extending in planes making an angle of 60 witheach other, and connected at their lower ends by cross members 16 whichform an equilateral triangle extending in a plane at right angles to theplanes of the three ogival frames 15. The three frames 15 have commonsides 17, as clearly shown in Figure 5, the insert frame 4 is adapted tosnugly fit within the body 1 so as to engage the inside faces of thepanels 3 to hold them in proper position within their respective window5.

The body 1 and insert frame 4, together with the sleeve 13, may be madeof moulded plastic material. It is preferable that the outside of thebody 1 is covered with a metal layer such as tin.

The lamp shade is assembled in the following manner: the frame 4 isinserted inside the body formed by the folded sheet 2 (Figure 6) andthese two assembled elements are inserted through the bottom end of thebody frame 1 (Figure 7).

The lamp shade is secured to the socket A by inserting said socketwithin the sleeve 13 and inserting the bulb B through the bottom openend of the lamp shade and screwing said bulb within the socket A.

In use, cooling air will circulate through the lamp shade from thebottom opening defined by the bottom part of the insert, upwardly aroundthe bulb B and will be discharged through the apertures 12 made in theweb 11.

It is understood that an inside bulb is by no means essential and myinvention may be made without provision for it, particularly if it is tobe hung as an attractive ornament elsewhere than in a Christmas tree.

While a preferred embodiment according to the present invention has beenillustrated and described it is understood that various modificationsmay be resorted to 3 without departing from the spirit and scope of theappended claim.

I claim:

A larnp shade of the character described comprising a body frame havinga triangular cross-section and three windows of ogival shape made in theside faces of said body frame, a translucent sheet cut out to form threeogival panels connected along their side edges and inserted within saidbody with the marginal portion of said ogival panels in contact with theedges of said Windows, and an insert frame engaged Within said bodyframe and contacting the inside face of said translucent sheet to holdthe latter in position Within said body, said insert frame tightly andsnugly fitting said sheet and body frame, said insert frame consistingin three ogival frames interconnected at their lower end by a triangularframe, said.
